An ant colony started off with a total of 300 ants. after the ants began to leave the colony, there were 250 ants left after 2 minutes. using this information, how can you describe the rate of change in the number of ants in the colony per minute?

125 ants per minute

Step-by-step explanation: you are looking for the number of ants per 1 minute. you already have how many ants per 2 minutes, so you divide that by 2. 250/2 = 125

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

edit: i meant

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
